The HawkEye IR-5x Series is a MEMS technology pulsable infrared emitter. This
source is based on patented technology, utilizing a thin film resistor of diamond-like nanostructured amorphous carbon. Due to its low thermal mass, the IR-5x Series can be pulsed at frequencies up to 100+ hertz with good modulation depth (contrast between the on and off states).
The IR-50, mounted in a TO-5 header with a windowless cap provides a small package. The IR-50 uses a micromachined source chip with a thin, high-emissivity membrane.
The IR-50 can also be configured with optional windows, sapphire (-S, 0.7-5.0 um) or CaF2 (-CaF2, 0.15-9.0 um).
The IR-55 utilizes a collimated optic to provide more than 12x the on-axis output. The package is 0.5 inches in diameter and 0.65 inches long. FWHM (full width at half max) for the IR-55 is 15°.
Similarly, the IR-56 provides collimated output in a "short" parabolic design (0.4 diameter and 0.36 length). It delivers approx. 50-55% of the on-axis energy of the IR-55. FWHM (full width at half max) for the IR-56 is 20°.
The IR-57 utilizes a 1.0 inch diameter focusing elliptical optic.
